Abstract
The invention relates to a powdery dye composition consisting essentially of C.I. Pigment Red 170 (C.I. No. 12475) and barium sulfate, wherein the barium sulfate is added before or during the production process of the C.I. Pigment Red 170. The inventive addition of barium sulfate enables non-homogeneities and caking to be avoided in the mixture.
